I don't know whether this is related (perhaps since this involves
font settings), but a strace with xpdf 3.02-21 gives:
[...]
14121 open("/home/vinc17/.xpdfrc", O_RDONLY) = -1 ENOENT (No such file or
directory)

while with xpdf 3.03-4, I get:
[...]

This seems to be the first difference.
BTW, since the xpdfrc file is the current directory (if I understand
correctly) is read, this could be a security hole, depending on what
is possible with it.
